Essentially I gave up. I drain and clean out water barrel late fall and turn upside down over winter months. BUT, this takes care of water concerns spring, summer, and fall with little work involved. Mother nature fills it and I filter it and treat it with ACV. A heated water dog dish I have noticed at the feed store, comes in an extra large size. 2 and 1/2 gallons or 3, I think. Tempted to configure some fancy style water drinkers and cover the top to keep clean. With a little thought, this might work. Time to do some tinkering!
